5.6.4 Terminal assignment PSCBR-E-31-12DI-10DIO
5.7 External 24 VDC
– power supply
The PSCBR module requires a 24 VDC power supply with PELV characteristic in accordance to
EN50178. Please comply with the following boundary conditions when planning and installing the
specified power supply unit:
Strictly comply with the minimum and maximum supply voltage tolerance.
Nominal voltage
DC 24 V
Minimum: 24 VDC
– 15 %
20.4 VDC
Maximum: 24 VDC + 20 %
28.8 VDC
We recommend the use of a 3-phase power supply unit or an electronically controlled device to
achieve an as little as possible residual ripple of the supply voltage. The power supply unit must
meet the requirements acc. to EN61000-4-11 (voltage dip).
Connecting cables must comply with local regulations.
The interference voltage resistance of the PSCBR module is 32 VDC (protected by suppressor
diodes at the input).
